2. A. detachable device for operating the shift mechanism of typewritingmachines,

' attached to said rod for preventing longitu dinal'IDOVEBIIIBIllJlIhQIQOf; and a vertically disposed plate rigidly securedto said rod whereby the rod may be partially rotated and the shift leverdepressed by backward pressure on said plate.

In testimony whereof I afiix my signature, in the presence of twowitnesses.
